Question

Assertion (A): Mitosis is often called indirect division.

Reason (R): Mitosis divides a parent cell into two daughter cells.

Options

• Both A and R are true and R is the correct explanation of A.

• Both A and R are true but R is not the correct explanation of A.

• A is true but R is false.

• A is false but R is true.

Answer 1

Both A and R are true but R is not the correct explanation of A.

Explanation:

The assertion is true because mitosis is called indirect division since the cell undergoes complex intermediate structural transformations such as chromatin condensation, spindle formation, and nuclear membrane breakdown, rather than simply pinching in half. The reason is also true because mitosis always yields two genetically identical daughter cells from a single parent cell. However, this reason does not explain the assertion, as simply producing two cells does not explain how or why the process is structurally indirect.
